Patented Jan. 30,1912. Divided and this application led J'ne 5,

1911. Serial No. 631,273.

To all whom t may concern.' j

Be it known that I, Lotus BADER', a citi- Zen of the United States, anda resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements inGasometers, of which the following is a specification.

My invention relates to improvements in gasometers especially adaptedfor use in acetylene gas generators, the present application being adivisional application of my prior application for improvements inacetylene gas generators led November 25th, 1910, Serial No. 594,053.

The object of the invention is to provide an improved gasometer for usein acetylene gas generators.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawing forming a part of this specification and in which,

Figure 1 is a vertical section through the upper portion of a generatorand gasometer, a gas washer and carbid holder and feeding mechanismbeing shown in elevation, and Fig. 2 is an enlarged section takenthrough the upper portion of the gasometer.

The preferred form of construction as illustrated in the accompanyingdrawing comprises a gas generatorA 1 which may be of any usual ordesired construction. A gasoineter 2 is arranged on top of generator 1but not in direct communication therewith and a discharge pipe 3 alsoleads from the top of said generator. A gas cleanser 5 is arranged uponthe top of pipe 3 and a pipe 4 serves as a means of communicationbetween pipe 3 and gas cleanser 5 and a pipe 6 leads from the top ofcleanser 5 to the bottom of gasometer 2. The details of the gas cleanserform the subject matter of my copending application and need no furtherillustration or description here. An extensible bellows 7 is arranged ingasometer 2 above the mouth of pipe 6, the lower edges 8 of said bellowsbeing clamped to the walls of said gasometer as shown. The top ofbellows 7 is provided with a centralperforation 9 and a cap l0 issecured around the underside of said perforation 9 and is itselfprovided with, a

number of perforations 1l for the free pas',- sage of gas therethrough.A valve 12 which is normally held by a spring 13 in position to closeperforation 9 is mount-ed upon rods 14 which project upwardly therefrom.A

vent pipe 15 leads from gasometer 2 and serves to` permit of the escapeof gases passing through perforation 9. A cap' 16 is placed overperforation 9 and is" provided with perforations 17 for the free passageof gas therethrough. Cap 16 is perforated for the passage of arms 14which are arranged to Contact with the top of gasometer 2 when the topof the bellows 7 approaches the limit of its upward movement.

A rack bar 18 is mounted to reciprocate in the top of gasometer 2 and iscarried by cap 16, being normally held in elevated position by means ofa spring 19 imprisoned between cap 16 and a washer or collar 2O securedto said rack bar. Rack bar 18 is free for vertical movement relativelyto cap 16, its upward movement being limited by a collar or washer 21arranged to contact with the underside of the top of cap 16. By thisarrangement it will be observed that upon increase of gas pressure ingasometer 2 bellows 7 will be extended and rack bar 18 caused to rise.When the top of bellows 7 approaches the top of gasometer 2 arms 14contacting with the top of the gasometer depress valve 12 and permit theescape of a portion of the gas in said gasometer, thus relieving anyexcess or dangerous pressure. Should the rack bar 18 be held by anyaccident or other cause from traveling upwardly with the top of bellows7 the lower end of said rack bar will contact with valve 12 to open thesame and thus relieve any dangerous or excessive pressure. By these'means it will be observed that the pressure in gasometer 2 may bemaintained practically constant. Rack bar 18 meshes with a segmentalgear 22 carried by one end of lever 23 which at its other end carries asegmental gear 24 meshing with a crown gear 25. Crown gear 25 isconnected by means of a sprocket chain 26 with a carbid holder andfeeder 27 which in turn is connected by means of pipe 28 withgenerator 1. The details of the carbid holder and feeder constitute thesubject matter of my copending application and need no furtherillustration or description here, except the statement that they arearranged to supply carbid to generator l upon deseentof rack bar 18, orde crease in gas pressure in gasoineter 2.

A gasometer constructed as above set forth will be found to be highlyefioient and durable in use. 4

l/Vhile I have illustrated and described the preferred form ofconstruction for carrying .my invention into effect, this is Capable ofvariation and modification. without departing from the spirit of theinvention. I therefore do not wish to be limited to the precisedetailsof construction set forth, but desire to avail myself of suolivariations and modifications as come within the scope of the appendedclaim.

Having described my invention what ll elaiin as new and desire to secureby Letters Patent is:

A gasolneter comprising an outer shell i and a bellows adapted to beextended by pressure of gas fed to said gasoineter; a rack connected tosaid bellows, said rack being spring held; a relief valve in the head ofsaid bellows arranged to be opened by said rack upon interruption of themovenient of said rack; a spring normally holding said valve closed; anarm carried by said valve adapted to Contact with the end oi said shellto open said valve; and an operative connection with said rack,substa-ntially as described.

In testimony whereof I have signed my naine to this speoiiioation in thepresence oil' two subscribing witnesses.
